The former Blues defender told ESPN FC: “Well, to be really honest, and frank, no [Chelsea should not sign him].
“I think Coutinho is a good player and I'm not even trying to be harsh on him, I think I want to find Barcelona guilty for the situation because they put a price on Coutinho who I think doesn't belong to that league.
“Now it's hard to reverse the system, it's hard to think that you can even the price and accept to lose like £65m for a transfer.
“But if you check on the quality of Coutinho, of course he is a talented player, of course he is a good player, but does he belong to the top, top players? Allow me to have some doubts about that.
“When I see Neymar, when I see [Cristiano] Ronaldo, when I see [Lionel] Messi, when I see [Kylian] Mbappe, I see top, top players.
“Coutinho has a price of a top, top player and I don't want to make a statement but I'm not sure he has the quality of a top, top player.
“And now, how do you reverse the system? How do you put Coutinho in a team and how do you rate him now?
“You talk about Chelsea, ready to [pay] £80m. I think it's too much for a player where you're not sure he's going to find the level he was, he used to be, at Liverpool and is not anymore.
“That's why I think Coutinho shouldn't go to Chelsea because there is no room for him and I think it is too much to spend for a player where we don't know the standard.”
